com.webos.service.location

API Summary

Provides basic location services for single or multiple position fixes. This service connects to Luna bus to interact with other system components (e.g. apps, services) that require location services.

Overview of the API

Decides the type of location service provider based on the request parameters. Once a suitable location service provider is selected, the service uses the location service provider to construct positions fix(es). webOS uses the following location service providers for position fixing:

GPS / AGPS
WPS / CellID.
Geocoding / Reverse geocoding (prerequisites : check "Google Geocoding API Key" section below)
Mock: Enables to test location features with fake information.

Note: The location service provider is also called a location source and location handler.

Google Geocoding API Key

To use the GeoCoding functionality, you must have the Geocoding API keys to authenticate requests associated with your project for usage and billing purposes. You must perform the following steps:

Sign up and create a billing account with Google Maps Platform.
Follow steps to get GeoCoding API key.
Encrypt generated GeoCoding key with base64 encoding, execute following command in terminal
$ echo "GEOCODING_KEY" | base64
<<ENCRYPTED_GEOCODING_KEY>>
Write encrypted key in file /etc/location/wsp.conf present on your device. Create following file:
{
  "wpsName": "google",
  "apiKey": "ENCRYPTED_GEOCODING_KEY",
  "services": [
  {
  "features": ["geocode", "reverseGeocode"],
  "url": "https://maps.googleapis.com/maps/api/geocode/json?"
  }
  ]
}
If the location service is already running, reboot the device.
